When something is to a negative power, you switch the fraction. I would then equal 3/1, to the power of 2. 3/1 is 3, so its just 3 to the power of 2.
The answer then is 9...

This is an actually good game. You have to actually think for it. Let me try one.

-3x+10=55, this one is easy. What does x equal?

x=-15

I don't learn math in english so can someone please explain what does "to the power of.." mean?

edit:oh I have to post one

x squared - 3x + 9=0 an easy one

x1=? x2=?

uh.... unless I'm doing that wrong, it's unsolvable unless you solve it as an imaginary number.

When someone says "to the power of" they are referring to the exponent.

EX: x³ is x cubed, or x to the third power.

x² -7x + 12=0

I suck at the quadratic formula. Here's one you can do in your head.

yeah yesterday, when my comp was already off the number should 9 was wrong.. it should have been 4 or something solvable..

x1=4 x2=3

here's a really easy one

y-x=4
-2y-x=6

Really easy? Ha! I had to learn how to do it online. I couldn't remember. lol

Y= -2/3 X=-4 2/3

Two points on a cordinate plane are: (2,4) and (-3, -3)

What is the slope?

Bonus!: Who invented the cordinate plane?

I used the two points to find the slope then figured it out in point slope form but yeah i got

y=7/5x+4/5

heres one

2 is what percent of 40

$1.26

Here's a hard one, well I thought it was hard, but it's off of my practice test that I had to do today. Good luck solving it.

Pamela Ferguson was setting up two aquariums in her new office. At the pet store, salt water fish were priced at $4 each and fresh water fish were priced at $3 each. She bought some of each kind and paid $58 for a total of 17 fish. how many fresh water fish did she buy?

10 fresh water fish, and 7 salt water.

I'm horrible at those...but for some reason, I saw the answer instantly in my head.

Alright,

What's the distance and midpoint of these two points: (2,5), (-4,-1) ??

Distance: sq. root 72
Midpoint: (-1, 2)

f(x) = 8x - x^2

Find: f(6) and f(c+4)

I need help with that.

I'll do some easy algebra.
2(x+4)=50
